Title: Extended floats for hydroelectric unit - have spindle adjustable water tight external tubular chambers for immersion depth adjustment
Inventor: SCHUSTER JOHANN
IPC: F03B17/06
Filed: 1976-02-14
Abstract: Extended floats with a mechanically regulatable immersion depth, the depth being adjusted by flooding of the hollow chamber, but also can be achieved by the fact that on the outside of the floats there are water tight tubular sleeves (2) over its whole length. These can be moved in a vertical direction by spindles, and the spindles (3) can be used to adjust the immersion depth accurately. The volume of the movable sleeves is determined by the total weight of the floating unit. The extension of the floats side walls inclined outwards, also on the outflow side, effects a further increase in the current speed in the water trough. Flow from the trough is not restricted by laterally flowing water since no water build-up can be formed.

Patent DE-2634685-A1 (DE)
Title: Water injection for IC engine - takes place before, during and after combustion to increase efficiency
Inventor: HESSE KLAUS
IPC: F02M25/022
Filed: 1976-08-02
Abstract: Water is injected into the cylinders of an internal combustion engine as a finely divided spray. It vapourises during the engine cycle and the resulting steam raises the total pressure within the cylinders. This makes it possible for combustion to take place with a smaller quantity of fuel since attainment of combustion conditions is not dependent on compression of the fuel alone. The water is injected before combustion occurs. Further water can be injected during combustion and again after combustion has taken place. The steam produced is condensed from the exhaust gases cleaned and returned to the reservoir for reuse in the injection process. The injection takes place during a working stroke without fuel.

Title: Enzymes sepn. from cells after solubilisation - by partition in multiphase systems contg. polymers
Inventor: KULA MARIA-REGINA DIPL CHEM DR
IPC: C12N9/26
Filed: 1976-08-31
Abstract: Sepn. of enzymes from cell (residues) is carried out by solubilising the enzyme and partitioning the enzyme, together with insoluble cell materials and cell fluid, between the various phases of an aq. multiphase system contg. either (a) >=1 high-mol. -wt. cpd. (e.g. an opt. substd. polyol; polyether, polyester, polyvinylpyrrolidone or polys saccharide) and at >=1 inorganic salt, or (b) >=2 high-mol. wt. cpds. The phases are then sepd., and the enzyme is sepd. from the high-mol. -wt. cpd. and opt. isolated. The process can be used to separate, e.g. aminoacyl t-RNA synthetases from E. coli, maltose from brewer's yeast, or pullulanase from Klebsiella pneumoniae. It is not necessary to remove the cell fluid before the multiphase partition treatment.

Title: Resistance spot welding cylinder - with ball non-return valves for gentle approach and high welding thrust
Inventor: LAUN VOLKER
IPC: B23K11/31
Filed: 1976-11-12
Abstract: A working cylinder, e.g. for resistance spot-welding, has a piston which is advanced pneumatically against the reaction of a vacuum until its electrode rests on the workpiece. The higher pressure which is then built up opens a spring-loaded valve between the vacuum and the pressure chamber and produces the higher pressure required for welding. This reduces the noise produced by the impact of the electrodes with the workpiece to permissible limits. It is a simple and effective means of combining a gentle approach with adequate welding thrust and fast return.
